24Ao Rear Panel
1. The 24Ao is equipped with an auto-switching interna-
tional power supply.
2. BNC word clock jacks. Use them for a variety of applica-
tions, such as digital transfers with devices that cannot
slave to the clock supplied by their digital I/O connection
with the 24Ao.
3. These three ADAT optical “lightpipe” jacks provide 24
channels of 24-bit ADAT optical digital I/O at 1x sample
rates (44.1 or 48 kHz) and 12 channels at 2x sample rates
(88.2 or 96 kHz). They are disabled at higher sample
rates. The IN and OUT ports on the right provide channels
1-8 (or 1-4), the left-hand ports provide channels 9-16
(or 5-8), and the third bank below provides channels
17-24 (or 9-12).
4. These three 8-channel banks provide 24 channels of
balanced analog output. You can use either a standard
8-channel Panasonic/Tascam format DB-25 cable or the
two 4-channel Phoenix connectors. DO NOT connect both
the D-sub and Phoenix connectors for a bank at the same
time. You can, however, use different connectors across
banks, if needed (for example, D-sub for channels 1-8
and Phoenix for channels 9-16). The pin-outs for the
Phoenix connectors are indicated on the label of the
connector; for the D-sub pinouts, see Appendix D, “D-sub
Connector Specifications” page (85).
5. Connect the 24Ao to the computer with this USB 2.0 port
using a standard USB cable. You can connect it to a
USB 2.0 or 3.0 port on the computer.
6. This AVB ethernet port provides industry standard IEEE
802.1 network connectivity to other network devices.
Examples include:
■
Another 24Ao or any other MOTU AVB-equipped audio
interface, such as the 1248, 8M, 16A, 24Ai, 24Ao, 112D,
Monitor 8, etc.
■
A standard ethernet hub or Wi-Fi router (for internet
connection and communication with the MOTU AVB
Control web app software).
■
A standard AVB Ethernet switch for high-speed, low-
latency, high-capacity audio connectivity to an AVB
audio network.
■
A recent-generation Mac (any Mac with a Thunderbolt
port) running OS X Yosemite (10.10) or later. This allows
you to operate the 24Ao as an audio interface over
Ethernet.
7. Use a standard (AES-59) Panasonic/Tascam DB-25 cable.
8. Make sure the retaining screws have standard 4-40
threading (not metric threading).
9. These are the pin-outs for the D-sub connector.
